In China, if catering enterprises use trademarks that are very similar or identical to those of other enterprises or other brands, it may cause confusion and misunderstanding among consumers and infringe upon the legitimate rights and interests of other enterprises or individuals. Therefore, in general, the same signboard cannot be used for trademark registration and use by other enterprises or individuals. If catering enterprises want to use a trademark that has been used by other enterprises or individuals, they need to obtain the authorization or permission of the trademark.

In the process of trademark use, it is also necessary to abide by relevant national laws and regulations, and pay attention to the scope of trademark use and brand image.
